Question

您好，我的代码存在一些问题，因为动画在这里工作了我的代码：

  background-image:url(industry2.jpg); 
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;
  border:1px solid red;
  -webkit-animation: fadein 2s ease-in ;
  -moz-animation: fadein 2s ease-in ;
  animation: fadein 2s ease-in ;
  width:500px;
  height:200px;
  background-repeat: no-repeat;
  background-position: left top;
  padding-top:68px;
  position:absolute;
  top:2700px;
  left:1300px; 

@keyframes fadein {
from { opacity: 0; }
to { opacity: 1; }

你知道我没有让动画工作，我也不知道该做什么......

Answer 1

您尚未关闭@keyframes。我已移除了左侧和顶部位置以便查看。

.container {
  background-image: url("http://via.placeholder.com/500x200");
  background-size: cover;
  border: 1px solid red;
  animation: fadein 2s ease-in;
  width: 500px;
  height: 200px;
  background-repeat: no-repeat;
  background-position: left top;
  padding-top: 68px;
  position: absolute;
}

@keyframes fadein {
  from {
    opacity: 0;
  }
  to {
    opacity: 1;
  }
}

<div class="container">Hello</div>

用CSS很麻烦
